'I'he invention relates to an improved apparatus forfthe manufacture of cigar-fillers.

Up till now it was rather difficult to make cigarfillers and more particularly those of a larger size, having a uniform compactness of'tobacco, which is of primary importance particularly with respect to the regular burning ofthe. cigar.

The vapparatus according to the invention en.-

`tirely realizes this object in that a. reciprocatingV rake-shaped pressure mechanism with 1 fingers controlled by springs is provided, by which means the tobacco is pressed under a certain pressure from a hopper into a metal tobacco-mold. 'I'he tobacco may then be cut oi, after which the con- Atents of the moldmay be pressed by means ofl a stamping-device into a wrapping-cloth to be wrapped in' the usual manner with a bunchwrapper or binder intol a ller. The tension of the springs of the fingers associated therewith can be' adjusted, and moreover the movement of the pressure mechanism is such that the fingers are ineffective at the upstroke, while at the downstroke'they press the tobacco from the interior Y of the hopper into the mold.

In this way a considerable advantage is'obtained as theV tobacco is perfectly equally divided into the mold, while the compactness of the ller can beV increased or reduced by changing the tension of the springs.

In orderto be able to remove the tobacco from the mold this'is moved 'rst horizontally from below'thehopper to the stamping-device and next verticallyA to reach the wrapping-cloth, -:Tfter which thetobacco is removed from the mold into the wrapping-cloth by means of a stamp.

According to the inventionthe.stamping-device comprises a bow which is guided by two vertical rails so as to be capable of motion to and from the wrapping-cloth, a stamp made of wood or similar material, and a spring between the bow and the stamp which permits the stampto continue its vertical movement to a certain extent` `after the'fbow has reached its lowest position.

In the drawings I vindicates the frame-of the machine on which the shaft 3 with its ily-wheel, 2,which is driven by any suitable means, is mounted. This shaft 3 drives a shaft 8 provided withI a toothed segment I by means of a chain 4 and sprockets 5 and 6. By rotating the toothed segment I a revolving motion periodically is com.- municated to the pinion I0 fixed on the shaft 9, which motion is transmitted by the shaft 9 onv which are secured both the drivingwheels `I I, I2 and a crank I3. The crank-pin I4 and the-crank I3 are connected with a rod II provided with fork-shaped ends I5 and I6 ofv whichthe forkshaped end I5 is hinged with a'rod I'which in its turn is linked by a hinged connection to two plates fixed to the tabler I9. The other forkshaped end I6 of rod I'I is provided with a shaft having a numberV of say six fingers 2I mount-v ed pivotally thereon. The slightlypointed extremity of each finger extendsthroughaslit 22 in the lower part of the hopper'23 containing the tobacco, whereas the other end is connected to aspring 24. Moreover said springs;24:are connected to a rod 25 which, by meansxof.: the nutsx21 screwed on the bolts 26, may be adjusted higher or lower either to increase or reduceithetensionof machine on which the shaft Swith' its fly-wheel the spring. A vertically placed;plate ZBembracin bolts. 26 and is held tightly in place'by nuts 29.

On each side of the hopper 23.the'periodicallyV revolving. supplying-bands -3'I v andf 32 are 'placed which are drivenby means of the belts and r36 from the shaft 9 by the pulleys II, 33fand 34. The shaft 9 is driven as elsewhere stated, by the shaft4 I0 to which a periodicmovement is imparted by the segment 1. Byvmeansofvthe pulleys- I2 and 37 and the belt 38 a roller 40 is periodically being rotated round the shaft 3'9for'guiding the tobacco from the bottom-of thehopperinto the tobacco-mold 41. A knife 4I (Figs.l 1 and 2) which is fixed to a rod 43 pivotally mounted at 42, is held'inV its utmost left position (i. e. not active) by'a spring 44 and at definite periods driven tothe right-hand sideby meansof a rod 45.

Said rod 45 which pivots at 46 is driven by any 652 suitable means, e. g. by means of a cam on the shaft 3.

In order to supply a definite amount of tobacco, the apparatus according to the invention has 5 an open metal tobacco-mold 41 of which the bottom is formed by the table I9 over which the mold is horizontally movable. This horizontal movement is periodical and is effected by means of a rod 48 pivotally mounted at 50 and having a fork- 10 shaped end 49 and a Vcam on the shaft 3; the rod 48 is continually being pressed against cam 3 by means of a spring 48a. The fork-shaped end 49 is provided with a projection 5I which fits into a recess 52 of the tobacco-mold 41. The part to V be filled with tobacco may have the shape as rep- 41 is situated below the stamping-device of which Y the principal features are a bow 53, that can take up the mold 41 and a stamp 54 made of wood or similarV material that is fixed to a plate 55. To

this plate 55, above the stamp 54 a shaft 56 is mounted, having at its top a guide 51 round which Y shaft 56 between the stop 58 engaging the bow 53 and the plater55 a spring 59 is provided. The

bow 53, which can move vertically along rails 68 of the vertically projecting posts 6I, is provid- 3Q ed at the lower end with two supports 62 for the mold 41. The vertical movement of the stampingdevice is effected by a roller 63 on the toothed segment 1 (Fig. l) which cooperates with a tongue 64 on the lever 66 pivoted at 65, which in its turn communicates the movement to the link 61 and lever 68. Lever'68 turning at 69 is provided at its end with a roller 10, that rolls along guide 51 on spindle 56. In order to place bow 53 with its mold supports 62 at the right height, yan

adjustable stop 1I is placed below lever 66; lever 66 is constantly pulled down by spring 12.

For wrapping the cigar-filler, a container 13 is placed under the stamping device to which a. board 14 is fixed; just over it a roller 15 is movable, which is xed to two rods 11 guided in tubes s 16 which in their turn can be moved periodically by a system ofrods 88 and 88 pivoted at 18 and 19 and connected by link 80' and for instance a cam on the shaft 3. Spring 8l presses the rod 80 continually to shaft 3. Over the container 13, roller 15 and the board 14, wrapping cloth 82 is placed which can be rolled up more or less by the roller 84 revolving on spindle 83. l

The apparatus according to the invention functions as follows:

` In the position of the toothed segment 1 shown in Fig. 2 the mold 41 is situated under the hopper 23. If the toothed segment 1 is set in motion in the direction of the arrow (Fig. l) shaft 9 V makes a number of revolutionse g. threewhile the supply belts 3I, 32, the roller 40 and crank I3 are moved too. The rake-shaped pressure-mechanism I1 thereby is alternatively lifted and dropped three times so that the fingers 2| at the down-stroke press the tobacco from the hopper 23 under a certain pressure into the tobacco mold 41. However during the up-stroke they remain outside of the slits and therefore do not affect the' movement of the tobacco.

7o AsY soon as the toothed segment 1 has passed the `*pinion I0, the fingers 2I stay at their topheightv and. the tobacco is then cut off by the knife' 4I. Next the tobacco-mold 41 filled with tobacco is pushed along the table I9 by means wrof rod 48 to the stamping-device. The knife however remains in the position as given in Fig. l in order to prevent the tobacco from dropping from the hopper while mold 41 is removed.

At the moment that mold 41 has arrived under the stamping-device, roller 53 of the toothed segment 1 is in front of the tongue 64 of lever 66. The movement being continued, cam 64 is pressed down and with it stamp 54 and bow 53 together with the tobacco-mold 41 on it. After the support 62 has arrived at therbottom of the con- 10 tainer 13 the downward motion continues for a short time so that against the pressure of spring 59 the stamp 54 is pressed through the mold 41 lled with tobacco and into the wrapping-cloth.

Spring 12 presses lever 66 again on stop 1I so that the stamp retakes its position over the mold and at the level of table I9. While the mold is moved back to the hopper 23, roller 15 under the wrapping cloth 82 is moved to the right so that in the normal way the filler is wrapped in 8,20 binder.

When the mold is under the trough again, th knife 4I is pulled back bythe spring 44 .and its rake-shaped pressing-mechanism can againsperform its upand downward movement. 25
